Abstract
The glory of a nation is influenced by the quality of its human resources. Human resources depend on the quality of their nations education. Teachers are an important part of developing the quality of education. Reliability of teacher competence contributes positively to the development of quality education. In fact, the results of the Teacher Competency Test (UKG) in Indonesia are still relatively low. The low quality of teachers results in low graduates, especially SMK graduates. In Bandung District unemployment is dominated by SMK graduates. Therefore, professional development of SMK teachers is needed, so that they have adequate competence, including being able to develop learning innovations. Lesson Study is one of the learning innovations that can improve cognitive, didactic, and pedagogical knowledge. Lesson Study can improve the mathematical disposition of teachers and students. This article discusses the description of the lesson study process and the mathematical disposition of students after learning through lesson study with a problem based learning approach.

Abstract
The binomial distribution is one of the discrete probability distributions that the application is easy to found in everyday life. Therefore, now, binomial distribution began to be introduced in mathematics learning at senior high school. The problem is the literacy provided by schools does not optimize the concept of binomial distribution itself. This research is a descriptive analysis that aims to describe the problems in one of the books in senior high school with the subject is binomial distribution. Based on the analysis that has been done, there are several problems, such as (1) the discussion scheme is less structured and there are several important concepts that are not given; (2) the description of statistics on the binomial distribution is less detailed (in this case mean and variance). The results of this analysis are expected to be one of the references for book developers to create books with discussions that optimize students conceptual understanding, especially in binomial distributions.

Abstract
Mathematical abstraction is a cognitive process when students construct their mathematics knowledge. This study explores mathematical abstraction of students related to the concept and the area of triangles. For this reason, firstly, the researchers developed four questions. This study was conducted in one junior high school in Bandung. Twenty three students, grade 7 (12-14 years old), were involved in this study. Data were collected through observation of the test results and followed by students- interviews. Finally, data was analyzed qualitatively. The researchers found that the low-achievement students tend to understand the triangles which consist of the interior area bounded by three straight lines and the lines themselves; they also tend to understand the area of triangles as the result of pattern of a base times height divided to two. Besides, there are indications that low-achievement students need help from teachers so that they can achieve higher level of abstraction.

Abstract
This study intends to investigate didactical and epistemological obstacles that occur when students solve the problem on the topic of geometry transformation. The data were collected from students- answer and interviews of 16 ninth graders and 16 twelfth graders when solving the test instrument used is five contextual problems and three problem description of geometry transformation. The data analysis reveals that most students have difficulty identifying contextual problems related to geometry transformation; not quite firm to know the characters from each type of geometry transformation (reflection, translation, rotation, and dilation); use procedural knowledge rather than conceptual understanding; and forget about the previous material related to geometry transformation. These findings are expected to overcome learning didactical and epistemological obstacles in teaching and learning of geometry transformation.

Abstract
Fraction is one of the important topic in mathematics learning that were still felt difficult by elementary school students, even by some middle school students. One of the proof was that there were students who experience misconceptions in the concept of fractions. This is one of the reasons for this research. The aim of study is to obtain a comprehensive description of students misconceptions in solving questions related to the concept of fractions. The subjects researched were seventh grade students of junior high school. This research uses a qualitative approach to the type of phenomenological research. Data collection was taken by observations, tests and interviews. The methods used to identify students who experience misconceptions were, using CRI (Certainty Index Response) that was given when students have worked on the test questions given. CRI can be used to classify students identified as having misconceptions, dont understand the concept, and do not know the concept. The results of data analysis show that there are students who do not know the concept of fractions, understand the concept of fractions, and experience misconceptions in the concept of fractions. Students identified as having misconceptions on the concept of fractions: part whole model; part group model; number line model. The factors that cause students to experience misconceptions are, 1) the ability of students to be wrong in: putting values for the numerator and denominator on fractions; determining the overall part of the picture; determining which fraction has greater value or fraction whose value is smaller, 2) errors in using addition operations in fractions, 3) errors in linking the concept of fractions in daily life.

Abstract
The main objective of this research is to develop a new didactic design that can optimize the development of students abilities, especially in the area of parallelogram and trapezium material. Didactic design was successfully developed throught three formal steps which was done by the researcher during the research process, namely didactic situation analysis before learning in the form of hypothetical didactic design including ADP, metapedadidactic analysis that is the implementation process of hypotetic didactic design, and retrospective analysis in the form of analysis linking the results of hypothetical didactic situation analysis with the results of an metapedadidactic that used to formulate empirical didactic designs. Composing the hypothetical didactic design is preceded by a preliminary analysis including studies of relevant previous researchs, analysis of learning videos, surveys of textbooks on school mathematics, theoretical analysis, and personalization conducted by the researcher. Design implementation is carried out in a junior high school in Bandung involving 94 students from three different classes. It is possible if the empirical didactic design which was produced in this study can be further developed through the same three formal steps

Abstract
This study examines pre-service chemistry teachers- understanding of concepts related to ionic liquids as cellulose solvents which include knowledge of cellulose, ionic compounds, and ionic liquids. This study used a descriptive method and involved 35 pre-service chemistry teachers from 6th semester who enrolled in the High School Chemistry unit. The research instruments of an open-ended questions which related to the concepts of ionic compounds, ionic liquids and cellulose. The results show that pre-service chemistry teachers have limited conceptions about of the concepts related to the dissolution of cellulose in ionic liquids. Based on the analysis of student answers to open-ended questions, students- conceptions about definition of cellulose are quite good, but student have no sufficient knowledge about the structure and benefits of cellulose. Furthermore, students- conceptions related to ionic compounds and ionic liquids are not good enough because student have not been able to mention the differences between ionic compounds and ionic liquids based on the structure, properties, and the constituent particles. This is because ionic liquids as cellulose solvents and the concepts related are not taught directly in the classroom so that it becomes an unfamiliar concept to student.

Abstract
We studied how the follows of Read-Answer-Discuss-Explain and Create (RADEC) sustained pre service teachers as a conception tool for knowledge integration in their science approaches courses. In this examining study, pre service elementary illustrated models of the process of teaching and learning, including what happened before, during, and subsequently teaching. Data sources included initial and final models, details of initial and final models, and pre- and post-interviews. We used the data integration framework to discover how the RADEC models of the process of teaching and learning changed conception supposed the value of modeling the process of teaching and learning. Results showed that developing models supported the pre service elementary teachers in participating lesson design into their conceptions of teaching, as the planning progression was previously an invisible component of teaching. Finally, across the pre service elementary teacher, we found they were able to identify weaknesses in their primary models and saw their individual growing in teacher knowledge. Overall, the RADEC valued the modeling activity and saw their models as a conception tool that facilitated them make sense of their methods assignments. Implications for teacher educators are given.

Abstract
The development and interest about mathematics textbooks in Indonesia have a considerable increase in last decade. In this study we discuss on structure analysis of Indonesian mathematics textbooks in Relation and Function Topics. In this study we focused structure analysis of mathematics textbooks for 8th grade students. Three Indonesian mathematics textbooks were analyzed for this study. An analysis framework was developed to investigate the characteristics of structure in the textbooks from three perspectives: the physical features, the schematic of the math contents in the textbooks, and the patterns in sequencing of content. We counted the distribution of block types, contents and performance expectation types to help us in examining and analyzing the structure of textbooks in relation and function topics for 8th grade. Our analysis showed that the three textbooks generally have a common structure. Firstly, the textbook A has more pages than the others. Mostly the textbook provided many learning activities with scientific approach. Secondly, the schematics showed that the brief of structure of the three textbooks which have a common structure: 1) illustration about relation and function; 2) a concept map; 3) a set of narrations, learning activities, worked examples, and exercise to help students in understanding the topics; and 4) a competence test to examine whether students have achieved the aims of learning or not. Lastly, the patterns in sequencing content of the three textbooks showed that they have different patterns. Based on the results, recommendations are given for investigating the linkage between structure of textbook and performance expectation in order to do further research in this topics.

Abstract
TThis study aims to analyze students preconceptions regarding the context of magnetic media lubricants and chemical content related to the context as the basis for didactic design development that can teach technological aspects in high school chemistry learning. Descriptive research methods are used in explaining the results of the research obtained. This study involved 40 students from one of the high schools in the city of Bandung. The preconception test questions are based on the magnetic media lubrication enrichment book used to gather information about students conceptions regarding the context of magnetic media lubricants and their understanding of context-related chemical content. The preconception questions consist of 17 questions. Student answers are analyzed using a frequency distribution to categorize the criteria of conceptual understanding of each question and the answers are analyzed for errors to show learning obstacles that might arise in learning. In general, the results show that students still have a limited understanding. Therefore, it is necessary for educators to develop a didactic design based on the findings of student learning obstacles so as to be able to integrate technology in science learning comprehensively and optimally.

Abstract
To survive in the 21st century requires a variety of skills. Achieving 21st century skills is conducted by updating the quality of learning, including in Biotechnology. Biotechnology is one of the subjects in Biology Education Study Program FKIP UNPAS Bandung, aims to provide as Biology teacher candidates that can apply, develop and disseminate science and technology professionally. The purpose of this study was to determine the learning process of biotechnology of students of Biology teacher candidates in the Biology Education Study Program. The method used was descriptive qualitative with a questionnaire consisting of 15 questions which are a mixture of questions in open and closed forms and also interviews. Amount 38 students and two lecturers were involved in this study. The results showed that the learning process in the Biology Education Study Program, FKIP UNPAS, still uses the classical method by teaching-centered learning system. Another finding that the enthusiasm of the teaching staff to develop themselves is very potential to encourage the improvement of the quality of the learning process in the near future. Evidently, although it is still centered on the instructors, lecturers have used a scientific approach, PPA models and power point media equipped with animated videos.

Abstract
Concept understanding is an individual process to master by receiving and understanding information obtained from learning process in behave, think and act. This study aims to determine the profile of concepts understanding that experienced by students about direct current. At the end, we can find out the extent of the influence of understanding concepts on students during learning process. The research design used in this study is research design mixed methods explanatory design . The design of this study is combination of qualitative and quantitative data. The stages of implementation in this study will be conducted at SMAN 11 Kota Jambi in class X with the concept which already taught is about direct current. The instrument of this research is conceptual questions in the form of multiple choice and interview transcripts. Moreover, the data analyzed qualitatively and quantitatively. The results showed that in trials using conceptual questions, the percentage of correct answers for number 1 and 7 indicators was 50% correct, then for the lowest question indicators there were questions number 2 and 3 with the percentage of correct answers which was 37.50%. The results of the field trials prove that there is still a low students concepts understanding regarding the concept of direct current

Abstract
The developing reflective thinking skills (RF) for pre-service teachers is very important. It made pre-service teachers try to integrate the ability to think reflective in the teaching process. The study aims to explore the ability of argumentation that has been constructed into the reflective thinking process. It purpose to enhance the reflective thinking capabilities of physics pre-service teachers- climate prediction material.The respondent of this research were three respondents. The data obtained in the form of arguments by determining claims, warrant and backing qualitatively. It analysed using descriptive explorative. Based on the results of data analysis, the pre-service teachers reflective thinking ability was seen from the results of the argumentation. We described three (3) different level for respondent reflective thinking capability in which the first respondent in resolution level, the second respondent in exploration level, and the third respondent in triggering event level. This means that the reconstruction of the reflective thinking process by including the arguments was very effective to explore the reflective thinking capabilities of pre-service teachers.
